I am to this point in the project it is 17 out at the moment so not working on it till this cold snap breaks. I have 6x6 posts with 2x4 purlins on the out side and osb walls with vinly siding.None of witch is completed. I want to put 1 1/2 pink foam in between each purlin before i sheet it and then r22 denim insulation after that. I have already built 2x6 walls in between each post. And it will be dry walled inside. So my question is do i need a vapor barrier any where beside the tyvek?

My thoughts are no, because no significant source of inside moisture. Are you planning to heat it with a torpedo or other non-vented appliance?

No. I do alot of side work and Building anything and everything. I am going to keep it heated all the time it will have 90% natural gas furnace. I will be in it every day and have a large fabrication table i dont want to rust or worry about heating up everyday. All of my benches are also 1/4 steel tops In my last building not keeping it heated all the time there was alot of condensation and rust. I also use to heat with wood stove never again lol.
